Almost 2,000 more trees will have to be felled this autumn and winter because of the continued spread of climate change fuelled disease.
Ash dieback is expected to infect nine in ten ash trees across the country, and 1500 have already been cut down in the last two years in Brighton and Hove.
Work has now started on felling hundreds more, with Stanmer and Wild Park set to lose a thousand later this winter.
Ash dieback thrives in warm, wet winters, which have become more common in recent years.
Up to 500 infected ash trees are being felled in Woodvale Cemetery and woods in the Bevendean and Moulsecoomb areas.
Work will then move to the Coldean area, where an estimated 300 ash trees and 100 elms need to be felled in the woods bordering the A27 and the neighbouring woodland.
Later in the winter, ash dieback work is needed in Stanmer Park and Wild Park, where our initial inspections indicate the loss of a further 1,000 ash trees.
While some of the trees may look healthy, they are infected with the fungal infection ash dieback and need to be removed as they pose an ever-increasing risk to both the public and property.
The council is carrying out wildlife surveys and following best practice guidance and wildlife regulations to minimise the ecological impact of the work.
It is warning the public to be extra careful in woodland areas due to the potential risk of falling trees and deadwood, especially during windy days.
A city-wide ash dieback regeneration plan has been agreed to enhance the city’s woodlands for the future.
The council will be planting 14,000 tree whips over this planting season in areas where it has had to remove significant numbers of ash trees last year.
Replanting plans for the woodlands affected by ash dieback removal this year will be shared with local communities and feedback requested.
Once the work begins, signage will be in place to keep the public safe and let them know what’s going on.
Tree tops will be left on-site, mostly to feed nutrients back into the area and provide habitat for the local wildlife. While it may look untidy, it has ecological benefits in the longer term.
Tree stems will be removed from site where possible, but there may be areas where access is trickier where we need to leave some large pieces of timber.
Some young ash trees not showing signs of ash dieback will be left and observed for resistance, and a selection of mature ash stems will be left at height as stumps for wildlife habitat.
Where diseased ash trees are difficult to remove without machinery, the council may need to remove other tree species to gain access to these areas.
One of our tree officers will be inspecting these areas and it’s our priority to limit the amount of non-ash trees that are removed to an absolute minimum.
The council will also be inspecting the sites for diseased elm trees and will remove those deemed a risk to the wider elm disease control programme.
It has been granted felling licences where required from the government’s Forestry Commission. These must also include plans for the restocking, regeneration or improvements to each site before the commission will issue the licence.
Ash dieback is a tree fungal infection that’s spreading throughout the UK and Europe. The National Trust, the Woodland Trust and other environmental organisations predict the disease will kill between 80 to 90% of ash trees across the UK.
Like the rest of the country, and especially the south-east, high numbers of our ash trees are infected by the disease, which is impossible to contain.
Ash dieback is driven by the climate crisis. Mild, wet winters create ideal conditions for disease and pests to spread. Prolonged drought, flooding and high temperatures also mean that the trees are likely to be stressed and more vulnerable to disease.
While the city has relatively few ash trees within more urban areas, around 20% of all woodland trees managed by the council are ash.
The city has already lost hundreds of trees to the devastating disease and, with an estimated 75% to 80% of ash trees throughout the country expected to die within the next 5 to 10 years, we’re anticipating our woodlands will look very different as a result.
As part of our ash dieback regeneration plan, the council will be planting 14,000 tree whips in the key areas we’ve previously had to clear of ash dieback infected trees.
This includes areas of woodland in Woodingdean, Moulsecoomb, Coldean and Westdene, as well as Wild Park, Coney Wood and the ‘Three Cornered Copse’ in Hove.
The tree planting programme is being paid for with £1 million from the council’s Carbon Neutral Fund.

Councillor Jamie Lloyd, Deputy Chair of the Environment, Transport & Sustainability Committee, said: “It’s devastating we’re losing so many of our trees. Like many other areas, ash dieback is having a terrible impact on the city’s woodlands.
“Sadly, we have no alternative but to remove all the infected trees to tackle the infection and keep our woodlands safe. There’s a huge amount of work to do over the next few years.
“It’s our priority to ensure the felling has the minimum impact possible on our wildlife and natural habitats.
“We do now have the regeneration plan in place to protect our woodlands for the future. It is great to see we’ll be planting 14,000 tree whips this season to start regenerating the woodlands already affected.”
